To all whom it may concern} i I Be itknown that I, FRANK A. BAKULA, acitizen of the'United States," residingat the city of St. Louis, Stateof Missouri, ha'veiri vented a certain new and useful Improvement inElectric-Lamp Fixtures, of which the following is a full, clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the same, reference being bad to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a vertical sectional View partly in elevation of my improvedlighting fixture.

Fig. 2 is a detail view of the attaching plate.

Fig. 3 is a detail view of one means of attaching the fixture inposition.

Fig. 4 is a similar view of a modified means of attaching the fixture inposition.

This invention relatesto a new and useful improvement in lightingfixtures, the

principal objects being to provide a reflectorj of translucent glasswhereby no shadows are cast on the ceiling and to provide an attachingplate which is universal in its application to various well known meansof attaching a fixture of this description in position.

In the drawings 1 indicates a reflector preferably made of whitetranslucent glass, said reflector consisting of a marginal flange ladapted to rest against the wall of the ceiling when the fixture isapplied directly to the ceiling, said marginal flange forming theterminus of a vertically disposed flange 1 the latter being connected toan upwardly curved wall 1 forming the bottom wall of the reflector. Thisbottom wall extends down-' wardly at the central portion so as toprovide angularly disposed supporting edges 1 with which cooperate aflanged metallic ring 2. This ring 2 is secured by screw eyes 3(preferably three in number) to an attaching plate 4:, the details ofwhich latter are shown in Fig. 2. This attaching plate is provided withvarious means of attachment susceptible of accommodation to differentlocations and means of securing the fixture in position. 7

As shown in Fig. 1, the fixture is secured directly tothe ceiling bymeans of screws passing through'the openings 4? in the attaching plate.As shown m Fig. 3, 5 represents an ordinary knock-out box having aiistemb arranged therein which stem extends down through an opening 4'in the attaching plate. This opening 49 is screw threaded in order thatthe attaching plate may be readily positioned on the lower end of avertically disposed rod or pipe when said plate is located a distancebelow the ceiling. As shown in Fig. 4:, 8 indicates an ordinaryknock-out box having. an inwardly extending flange for receiving thescrews which pass through slotst in the attaching plate. The attachingplate is also provided with threadedbosses A for the passage of screwsand openings 4 are also formed in the plate to permit the passage offixture wires. By the various means of attachment provided by the plate4, the reflector 1 is not only secured in position therein, but saidreflector may be used directly against the ceiling or wall, or as asuspended fixture, the plate being supported by a chain or chains.

9 indicates a socket support secured to the plate 4 and provides meansfor the attachment of a lamp 10. 11 indicates rods supported by thelower ends of the screw eyes 3, said rods in turn supporting a globe orbasket 12, (there being preferably threeof such rods used), such globeor basket being made preferably of translucent white glass and of suchshape as to reflect the rays of light from the lamp onto the undersideof the reflector. It is estimated that translucent white glass of theproper thickness will transmit about sixty per cent.- of the light raysand that forty per cent. of said rays will be reflected. Consequently,there will be no shadows cast on the ceiling by my improved fixturewhere it is used either as a direct ceiling light or as a suspendedfixture.

I am aware, of course, that still other modifications and adaptations ofmy improved lighting fixture may be made without departing from thescope and spirit of what I claim to be my invention.

What I claim is: r

1. In a fixture of the character described, the combination of a socketsupport adapted to receivea lighting element, a canopy supporting ringsurrounding said support, threaded rods for supporting said ring fromsaid support, a translucent canopy supported by said ring and having acentral opening through which said threaded rods pass, bowl rodsdependingbelow said ring, and a transpassage of attaching means, saidplate havmg means for the reception of screw eyes, a

supporting ring secured in position by said screw eyes, an upwardlycurved translucent reflector held in position by saidsupporting Intestimony whereofll hereuntoaflix my 15' signature, in the presence oftwo witnesses, this 16th day of August, 1917.
